Due to the large number of publications relating the occurrence of dental microcracks to endodontic procedures, this bibliometric study evaluated the scientific pattern and trends in literature and provided an overview of scientific production in this context.
To analyze, quantify, and characterize the scientific production and trends of published articles evaluating dentinal microcracks formation after endodontic treatment procedures between 2010 and 2020 using bibliometric indicators.
Published articles were found by the search in the Medline (PubMed) and Scopus database using the combination of the following keywords: Dentinal crack OR Dentinal Microcrack OR Crack formation OR Dentin Defect AND Endodontic treatment OR Root canal preparation OR Canal Preparation OR Root canal treatment OR endodontic procedures. The search was also conducted in the Journal of Endodontics and International Endodontic Journal. After inclusion and exclusion criteria application, data from all studies included were collected.
Among the 556 results after the search, 45 studies were included and analyzed in this bibliometry. No trend was observed in terms of the increasing number of articles over time. Most of them used an design, compared the effect of different endodontic techniques/systems for root canal instrumentation on dentinal microcracks formation, and were conducted in Turkey, Brazil, and India. Journal of Endodontics and International Endodontic Journal were the main journals with a higher number of articles published. Interestingly, studies conducted with some funding did not lead to higher citation numbers. Moreover, a relevant proportion of studies did not consider the inclusion of control groups, baseline evaluation, or statistical analysis. Micro-CT was the main technique used to evaluate microcrack presence.
Microcrack formation after the use of different endodontic techniques/systems has been constantly evaluated in the literature. There is a pattern of methodologies used, which may explain the concentration of these studies in specific journals and countries.
由于大量出版物将牙微裂纹的发生与牙髓治疗程序相关联，本文献计量学研究评估了该领域文献的科学模式和趋势，并概述了这方面的科研产出情况。
使用文献计量指标分析、量化并描述2010年至2020年间发表的评估牙髓治疗程序后牙本质微裂纹形成的文章的科研产出及趋势。
通过在Medline（PubMed）和Scopus数据库中搜索，使用以下关键词组合查找已发表的文章：牙本质裂纹或牙本质微裂纹或裂纹形成或牙本质缺陷与牙髓治疗或根管预备或根管制备或根管治疗或牙髓治疗程序。同时也在《牙髓病学杂志》和《国际牙髓病学杂志》上进行了搜索。在应用纳入和排除标准后，收集了所有纳入研究的数据。
在搜索得到的556条结果中，本文献计量学纳入并分析了45项研究。未观察到文章数量随时间增加的趋势。其中大多数采用了[具体设计]，比较了不同牙髓治疗技术/系统用于根管预备时对牙本质微裂纹形成的影响，且研究主要在土耳其、巴西和印度开展。《牙髓病学杂志》和《国际牙髓病学杂志》是发表文章数量较多的主要期刊。有趣的是，有一些资金支持的研究并未获得更高的引用次数。此外，相当一部分研究未考虑设置对照组、进行基线评估或统计分析。显微CT是评估微裂纹存在的主要技术。
文献中不断评估了使用不同牙髓治疗技术/系统后微裂纹的形成情况。存在一种所用方法的模式，这可能解释了这些研究集中在特定期刊和国家的原因。
